textBox1.Text.Insert(...) 方法不起作用

textBox1.Text.Insert(...) method doesn#39;t work(textBox1.Text.Insert(...) 方法不起作用)

问题描述

我正面临这种不正常的情况.以下代码无法正常工作:

I'm facing this abnormal situation. The following code doesn't work properly:

        string temp = "heythere";
        Console.WriteLine(temp);
        temp.Insert(3, "hello");
        Console.WriteLine(temp);

它不应该像heyhellothere"那样输出吗?但它确实heyrehere"(没有变化).

Isn't it supposed to output like "heyhellothere" ? But it does "heyrehere" (no change).

推荐答案

字符串是不可变的，它们不会就地改变.试试:

Strings are immutable, they don't change in-place. Try:

string temp = "heythere";
Console.WriteLine(temp);
temp = temp.Insert(3, "hello");
Console.WriteLine(temp);
